Adapted productive varieties and quality seed - Flagship Project 2 Overview, ISTRC 2018

  1. 1. O C T O B E R 2 0 1 8 Flagship Project 2: Adapted productive varieties and quality seed MONICA PARKER & MICHAEL FRIEDMANN • ISTRC MEETING, CIAT, COLOMBIA
  2. 2. Flagship overview Flagship project 2 (FP2) aims to make available good-quality planting materials of a diverse set of high-yielding RTB varieties that are adapted to the needs and preferences of different stakeholders in the value chain.
  3. 3. Clusters and Cluster Leaders Dr Jorge Andrade and Margaret McEwan CC2.1 – Quality seeds & access to improved varieties Dr Peter Kulakow CA2.3 – Added value cassava varieties Dr Inge van den Bergh and Dr Rony Swennen BA2.2 – User preferred banana cultivars / hybrids Dr Monica Parker PO2.4 – Seed Potato for Africa
  4. 4. Clusters and Cluster Leaders Dr Jürgen Kroschel PO2.5 – Agile Potato for Asia Dr Asrat Amele YA2.7 – Quality seed yam Dr Wolfgang Gruneberg SW2.6 – User preferred sweetpotato varieties
  5. 5. Key scientific achievements 2017-18
  6. 6. CC2.1 Quality seeds & access to improved varieties Toolbox to guide and refine seed system interventions
  7. 7. Ø Applied in potato, sweetpotato and cassava projects in Ethiopia, Kenya, Tanzania, Nigeria, Ecuador, and Georgia and India Ø Outputs include reports and papers: • structure and bottlenecks in existing seed systems • sourcing practices and seed flows • gender and seed policies • rapid multiplication techniques Application of Toolbox CC2.1 Quality seeds & access to improved varieties
  8. 8. Sensory and agronomic ranking of NARITA hybrids in Uganda and Tanzania BA2.2 User preferred banana cultivars/hybrids Farmers rank agronomic performance and prepared foods • identify important agronomic and sensory traits • gender preferences captured Generate quantitative score for each variety and a qualitative assessment of traits preferred and avoided
  9. 9. CA2.3 – Added value cassava varieties NOT PRUNED Accelerated in-bred parent lines for hybrid development through pruning Collaborators: • GuangXi Subropical Crops Research Institute (China) – developed idea • CIAT validated pruning technique and induced an earlier flowering • Cornell University – increase flower production with growth regulators • Induction of flowering reduces time to seed production from 12-16 months to 4-6 months • Goal: homozygous, self-pollinating cassava within only 6 years PRUNED
  10. 10. CA2.3 -BASICS-Cassava Seed Systems Project- Commercial Seed Flow Structure & Project Activities new improved varieties being disseminated via the pathways developed-including testing at processors at larger scale (up to 1 ton/variety)
  11. 11. • Profitable after 2 seasons of multiplication • Private sector investment: • $30,000 US to produce • $7,000 US in purchases • Officially recognized in seed certification regulations in Kenya Unica at 6 wks PO2.4 Potato for Africa 0.1 0.15 0.2 0.25 0.3 Cost (USD) Yield (# tubers) + minituber cutting 5 10 15 20 25 30 Apical cuttings continue to gain acceptance
  12. 12. India, Kufri Lima • Early, heat tolerant, and virus resistant • Allows 20-30 days earlier planting; extends the production window PO2.5 Agile Potato for Asia 2017 released varieties Bhutan, Yusi Mum (Unica) • High yield: 28-57 t/ha • Virus resistant; moderately field resistant to late blight • Population biofortified with Fe and Zn for subtropical midland and highland ecologies • >50 biofortified tetraploid clones distributed to Bhutan, Nepal, Kenya, Malawi, India, Peru
  13. 13. SW2.6 User preferred sweetpotato varieties • Scaling Fund awarded to scale Triple S PLUS (Storing in Sand and Sprouting) in Ghana and Ethiopia • Applying RTB tools to improve scaling readiness for Triple S • Gender responsive communication approaches & video based extension Use of Stepped Pits for Triple S for sprouting or root consumption, Ghana.

  14. 14. Model for variety development YA2.7 Quality seed yam Applied Accelerated Breeding Scheme • Select with clients in target environment • Spatial multivariate clustering of yam environments in West Africa for variety selection Linking to seed systems • Efficient technologies, aeroponics • based on PO2.4 cross-experience • Decentralized seed scheme
